Toall whom it-may concern: 7

' Be it known that I, BERT W. MILLER, a citizen of the United States, tesian, in the county of Sanborn and State of South Dakota, have invented certain new and useful Improvements in Sectional Wheel-Rims; and I do hereby declare the proved Wheel rim and scriptioh of the following to be a full, clear, and exact deinvention, such as will enable others Skilled in the art to which it. ,ap-

. pertains to make and use the same.

This invention relates to wheel rims and tires, and it. more particularly relates to a sectional wheel rim. An object'of the invention is to. provide a wheel rim which is adapted to be collapsed in order that certain forms of lion-stretchable tires maybe quickly and easily applied thereto. 1 I I The object and advantages of the invenset forth and then mr .In the accompanying drawings which form a part of this application, F gure 1 is a fragm'ental sectiona view through my imtire. Fig. 2'is a fra defined. in the appended I mental detail view taken on a plane'a't rig t edge and a flange 9 formed ed e, a circumferential vi ed between the flange 9 and the Lady of an les to the plane'on which Fig. 1' is taken, an Fig; 3 is aside elevationview of the pivotally'united outer rim member. I

Referring to the drawings in which simi: lar reference characters designate corre' s onding parts throughout the several views, t e numeral 5 designates a solid rim member which is connected with :1 spoke 6, in an ordinary manner. Secured upon-the periphery ofithe rim.5 is a metal'band or outer-rim support 7 having a flange 8 formed on one at itsopposite groove 10 being prothe band 7. The outer periphery of the I be fitted thereon; but, in the flange 9 is flush with the'outer periphery of the body of the band 7. 1 v 11 is seated in the groove 10, said flat ring being normally secured within the groove by any proper means (not shown). The periphery of the band 7, between the flange 8 and the ring 11 forms a seat for the outer rim 12. This outer rim may be of any req'uireu or desired shape, in cross scction,-according to the size and shape of the tire to present inresiding at Ar-.

A flat securing ring 7 shape that a tire of circular cross section would fit snugly within the tire seat 13 while theinner periphery of this rim is of such size and shape as to fit snugly upon'the rim seat between the flange 8 and ring 11.

I preferably form the outer rim 12 of three arcuate sections. 12, 12 and 12 pivoted together at 14 and adapted to be locked together by means of a slide bolt indicated at 15. The non-pivoted ends of the sections 12 and 12 are joined together on a plane at an angle to the radius of the rim, so that when the bolt 15 is disengaged from thesection 12, .the section 12 can be swung inward, in the direction of the section. .12", while the section l2 may be swung inward over the section 12', as indicated by the broken lines. It is readily seen that, when thus collapsed, this ring may be inserted within a tire of proper size, whereupon it may be expanded within the tire, so as to seat the latter in the tire seat 13, and the bolt 15 may then be brought into action for securing the rim in its expanded position. Havingthus been secured, the rim 12 may be easily: fitted onto the band .7 and secured thereon by inserting the ring 11 in the groove 10, any proper auxiliary securing means (not shown) being employed for preventing the rim 12 from rotating upon the band 7 In constructing shown, I preferably employ a long stripof spring metal wound into a helical coil, as

designated by the numeral 16, around this coil 16 is placed a strip of heavy canvas or duck 17 which extends parallel with the axis of the helical coil. rubber or rubber composition 18 is placed over the canvas, so that a tire of considerable resiliency and durability is obtained. Moreover, the time of ticclly' non-stretchable, and hence, it would be diflicult to force it upon an ordinar solid rim. It will be seen, however, that with my improved collapsible and demountable outer rim, the tire may be quickly and easily removed and replaced when necessary.

It will be seen th-at I have bination 'of parts which is ully capable of attaining the foregoing objects, "and'in a thoroughly practical and eflicientmanner.

I do not limit my invention to the exact details of construction, combination and ara' tire of the character An outer covering of this character is'pracrovided a comrangement of parts as herewith described i be limited section, the pivoted sections being movable inward one over the other and expansible Within a tire, said bolt serving to automatically lock the sections in extended annular form, said bolt being concealed within its section and disposed diametrically opposite the intermediate section.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
